Strong two-suiters
Two-suiters
A hand is a two-suiter if it contains: one suit of at least five cards and another of at least four To describe his two-suiter, the Opener must bid his 2nd suit at the 2 level
There are 3 types of two-suiter:
The minimum two-suiter, non-forcing with 12-17HCP. This allows the responder to stay at the 2 level when returning to the opening suit.
The reverse, forcing for a round with 17HCP or more. The second suit, bid at the 2 level, is higher-ranking than the first bidsuit. The responder is thus obliged to go to the 3 level to return to the opening suit.
The jump reverse, game-forcing, as from about 20HCP.

Problem E1212 1♠ Strong two-suiter : the Responder will be forced to bid at the 3 level in order to indicate preference for the Opener's first suit.
Strong two-suiter
A round forcing bid requires at least 17HCP .. as your Partner may only have 5
A round forcing bid requires at least 17HCP .. as your Partner may only have 5
- To bid a strong two-suiter, the lower ranked suit has to be longer than the higher-ranked suit.
- It's not possible to bid a strong two-suiter with a 5-5... because you have to open with the more expensive suit !
- Note that the weak two-suiter and the strong two-suiter overlap when the Opener has 17HCP.
- If Responder has bid at the 2 level, promising at least 11HCP, a strong two-suiter can be bid with 15HCP. The point count has now been lowered.

Problem E4829 2 ♥all the conditions have been met : 18HCP and a 5 carder which is a lower-ranked suit than the 4 carder.
Important!!!
Your strength doesn't always allow you to bid your two-suiter, especially when your 5 carder is a minor suit and not a major suit... Don't lull your Partner into a false understanding about the strength of your hand.

Be Careful! Important rule concerning the strong two-suiter
A strong two-suiter no longer exisits if the Responder has already bid a suit higher, thus disallowing Opener to rebid his suit at the 2 level.

Problem 20148 With this bidding sequence, Opener could have a 1st zone hand. Responder bids 2♦, ruling out the possibility of Opener to rebid ♣ at the 2 level. The aim of the 2♥ bid is to find the best contract.
